| Outline of Final Research Achievements |
Terahertz waves, located in the gap between radio waves and light waves, is the shortest non-ionizing wavelength region with high transperancy and specific absoption spectra for various polymers. In this research, we developed a detector with high sensitivity, broadband and large array capability in order to serve a new analytical tool of soft materials. Specifically, a microwave kinetic inductance detector (MKID) array based on not conventional metal superconductors but a high-temperature superconductor (YBCO) was developed. We also automated the data acquisition system from the cooling through the measurement. The larger format array offers the further improvement of the imaging capability and new application search of various functional polymers.
